This document is the Drain Basin Installation Guide. General information, field adjustments, product chart and photographs are included.

Nyloplast drain basins are custom built for each application. Our PVC products are more durable and corrosion-resistant than concrete or brick and mortar basins. With a faster installation, lower installed cost, and great field and project support teams, Nyloplast is the clear choice for your drainage needs.

Field Adjustments listed are Nyloplast Basins are lighter weight than traditional precast and are safer to handle and install. They also require a much smaller footprint to store the materials on construction sites.

Excavation around the structure is the same as the pipe trench width because Nyloplast Basins will allow for size on size pipe to structure connections unlike precast. Since it is very common for the actual elevation of the job site to deviate from the plans used to make a drain basin takeoff, Nyloplast drain basins are designed for easy adjustment in the field. In the event the elevation is less than expected, the drain basin can be cut down to size.

If the elevation is greater than anticipated, we offer riser sections of up to 6’ (1.8 m) in 1’ (.3 m) increments, which can be used to extend a drain basin.

Connecting pipes to Nyloplast structures in the field is made easy with “Add A-Branch” and INSERTA TEE® taps. Nyloplast will provide water tight connections to numerous types and diameters (4”-24” (100-600 mm)) of pipe in the field if angles or elevation changes occur.

Installation of Nyloplast requires no additional grout work or curing time and install 3-4 times faster than traditional brick and mortar or precast structures.

A chart listing part numbers and product descriptions and a step-by-step process in photographs is included.
